Measurement of the Wigner function of an ensemble of helium atoms

Article Abstract:

The measurement of the Wigner function of helium atoms formed by partially coherent illumination of a double slit has been reported and the negative parts in the oscillatory part of the Wigner function were identified. The reconstructed Wigner function's sheared appearance and regions of negative values close to the positive blobs are the consequences of the reconstruction algorithm.

Quantum mechanics: The truth about reality

Article Abstract:

The new measurements of quantum mechanics are expressed in hidden variables that have reconciled the purely statistical validity of quantum measurements with the classical world-view. Quantum information processing is very important in physics and computer science and hence it is vital to experiment on the foundations of the underlying theory.

Evidence for Efimov quantum states in an ultracold gas of caesium atoms

Article Abstract:

The observation of an Efimov resonance in an ultracold gas of caesium atoms is reported. The results confirm central theoretical predictions of Efimov physics and represent a starting point with which to explore the universal properties of resonantly interacting few-body systems.
